ananyo writes "According to the accepted account, an astronaut falling into a black hole would be ripped apart, and his remnants crushed as they plunged into the black hole's infinitely dense core. Calculations by Joseph Polchinski, a string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, though, point to a different end: quantum effects turn the event horizon into a seething maelstrom of particles and anyone who fell in would hit a wall of fire and be burned to a crisp in an instant. There's one problem with the firewall theory. If Polchinski is right, then either general relativity or quantum mechanics is wrong and his work has triggered a mini-crisis in theoretical physics."

Generally, yes it's not worth the time or the effort. However, if you're serious about taking advantage of your old drives, I'd suggest using RAID on top of LVM. LVM will allow you to group drives of different sizes together to form a logical volume. You can then use software RAID to ensure data integrity. Over time, as drives fail, you can replace failed drives with new ones and rebuild the failed logical volume. A simple Samba server should suffice for your file sharing needs.

The stock laptops do not offer an mSATA drive, so this issues is popping up with users putting in Intel/Renice/MyDigitalSSD third party drives — however all laptops are likely affected, whether the owners know it or not. The issue is not related to bios updates and may need a hardware fix. Ouch.Link to Original Source

If you're on a company network and you want to have a network performing okay while bittorrent clients are present on it, you'll need DPI.

That's complete nonsense. Bittorrent and other peer to peer networks are definitely bandwidth intensive, but you don't need DPI to maintain performance on a network. A properly configured QoS should be more than enough to balance things out. Simply prioritizing the outbound data by source address alone would ensure that anyone trying to perform bandwidth intensive tasks gets their fair share. IP protocols were designed to deal with bandwidth restrictions but also to use as much as possible. It's therefore possible that a few HTTP downloads could congest an entire network in the same way a bittorrent client does. This is becoming even more common with modern browsers which use multiple connections to try and retrieve data faster from remote servers.

The only thing DPI provides is the ability to restrict access to specific protocols based solely on packet content. If encryption is used, DPI is useless as it cannot differentiate between the traffic. The end result is a never ending war between software developers and network administrators. The final outcome has yet to be decided.

Several outlets reported on Wednesday that Samsung laptops had been found to contain a keylogger known as StarLogger right out of the box from the factory. However, upon closer inspection by security companies, the folder on the laptops that supposedly contained the malware was actually a directory that is part of Windows' multi-language support.Link to Original Source

Hugh Pickens writes writes: "The Christian Science Monitor reports that Japan has suspended efforts to prevent damaged reactors from melting down at the Fukushima Daiichi nuclear plant as a surge in radiation has made it too dangerous for workers to operate. "The workers cannot carry out even minimal work at the plant now," says chief government spokesman Yuko Edano, referring to workers who had been dousing the reactors with seawater in a frantic effort to cool down their rising temperatures. "Because of the radiation risk, we are on standby.""

darthcamaro writes: The new Linux 2.6.38 kernel is now out and it's got a long list of performance improvements that should make Linux a whole lot faster. The kernel includes support for Transparent Huge Pages, Transmit Packet Steering (XPS),a utomatic process grouping, and a new RCU (Read/Copy/Update)-based path name lookup.

"This patch series was both controversial and experimental when it went in, but we're very hopeful of seeing speedups," James Bottomley, distinguished engineer at Novell said. "Just to set expectations correctly, the dcache/path lookup improvements really only impact workloads with large metadata modifications, so the big iron workloads (like databases) will likely see no change. However, stuff that critically involves metadata, like running a mail server (the postmark benchmark) should improve quite a bit."

You and the author of the article both seem to be missing one important aspect of password hashing. You're never supposed to apply a particular hashing algorithm directly to a password. Instead the user's password should be combined with some salt(random data) and then hashed. The resulting hash can still be brute forced, but any resulting hashes can't be used as collisions for other stored hashes as they require a different known salt to be used. In other words, while it took the author 49 minutes he only had to compute 6^n number of hashes where n is the number of possible characters per position (lowercase, uppercase, numeric?). If each hashed password had a different known salt appended, he would have had to compute 14 * 6^n number of hashes. This is an order of magnitude larger than the original time. Of course, this only applies if the salt is known. If the salt is unknown during the brute-force it's practically impossible to discover the original password.

Sadly it seems a lot of people still think $10,000 is a briefcase full of cash. Lets break it down shall we.. Assuming they used standard US bills we get the following:

$10,000 = $100 x 100 bills = 1 stack of 100, $100 bills

$10,000 = $50 x 200 bills = 2 stacks of 100, $50 bills

$10,000 = $20 x 500 bills = 5 stacks of 100, $20 bills

$10,000 = $10 x 1000 bills = 10 stacks of 100, $10 bills

$10,000 = $5 x 2000 bills = 20 stacks of 100, $5 bills

$10,000 = $1 x 10000 bills = 100 stacks of 100, $1 bills

At 0:14 when they open the case you can clearly see several stacks marked as $100, some as $50, and some as $5. If the briefcase truly has $10,000 in it, the stacks marked with $100 bills must be filled with something other than $100 bills as a single stack would equal the amount the briefcase was said to hold. Given the variety of bills in the case, it appears they went to a lot of trouble to convince us that they gave away $10,000 USD. The reality is they probably didn't, and that the entire thing was just as staged as the briefcase full of cash.

I completely agree. Remove the word "lawful" from all sections and I'll be much more supportive of their efforts. If all content and application communications were protected under the First Amendment then word "lawful' would only serve to restrict that right in the future by designating specific things as "unlawful". The last thing we need is government overview of what applications or content are considered "lawful".

I thought gasoline taxes already accounted for this sort of thing. That is the more you drive your car the more tax you pay in taxes. If you're one of those idiots that must drive an 8mpg SUV then you undoubtedly pay more in taxes than someone who drives a midsized or compact car. Is this fair? I think so.
